उत्तर
Initiation codon of protein synthesis in Eukaryotes is AUG.
Explanation:
The codon AUG serves as the universal initiation codon (start signal) for protein synthesis in almost all eukaryotes. When the small ribosomal subunit scans the messenger RNA (mRNA) strand, it identifies the AUG sequence to establish the correct reading frame for translation. In addition to acting as a “tart” command, AUG also codes for the specific amino acid methionine, which means that most newly synthesised eukaryotic polypeptides begin with methionine as their first building block.
